I'm osessed with this gadget, but having gotten all Iphone gadgetry,
I"ll have to wait to get this one.
"Tenori-On is a new Yamaha prototype. It's a "personal digital instrument for playing sound and ambient light patterns." It has 256 light-topped buttons, stereo speakers, a scroll wheel, a few more buttons built into the frame, and some wireless function, so multiple Tenori-Ons can jam together. Looks awesome. Not many details, yet, but judging from the sine-wave blips on the Japanese Product Page, it could be the modern day Triadex Muse. More details at: WMMNA and Siggraph."
